How to validate XML against XSD in Java

[Shrinivas Mujumdar]

hello friends,
I have one doubt:
How to validate XML against XSD in Java?, I am using jdk 1.4.2_08.
One more thing is apart from jdk 1.5 where i will get the support for package javax.xml.validation

Thanx in Advance

You can use JDOM...

It will make document of XML only if it is valid...

JDOM APIs is not in JDK, you have to take jdom.jar into class path.

Ya I forgot the Crimson parser that comes bundled with java 1.4 does not support validation against schema

Regarding the first question any latest version of the xmlAPIs.jar and xercesImpl.jar from the apache website ought to do the trick

I think rather than relying on xerces api it is better to rely on Jaxp features

so maybe using code snippet is a better idea

DocumentBuilderFactory factory = DocumentBuilderFactory.newInstance();
 
Document doc = null;
 
try
{
 
factory.setAttribute(
"http://java.sun.com/xml/jaxp/properties/schemaLanguage",
"http://www.w3.org/2001/XMLSchema");
factory.setAttribute(
"http://java.sun.com/xml/jaxp/properties/schemaSource",
"test.xsd");
DocumentBuilder parser = factory.newDocumentBuilder();
doc = parser.parse(xmlFile);
}
catch (ParserConfigurationException e)
{
e.printStackTrace();
}
catch (SAXException e)
{
e.printStackTrace();
}
catch (IOException e)
{
e.printStackTrace();
}
return doc;
